This invention relates to a carpet roll handling device.

The invention has for an object to provide a novel and improved carpet roll handling device particularly adapted for handling large heavy rolls of carpeting during the cutting and laying operation whereby to facilitate handling of the carpet rolls and to enable the carpeting to be measured, cut and laid in a rapid and economical manner.

The invention has for another object to provide a novel and improved method of handling heavy carpet rolls during 'the carpet laying operation.

With these general objects in view and such others as may hereinafter appear, the invention consists in the carpet roll handling device and method hereinafter described and particularly defined in the claim at the end of this specification.

In the drawings illustrating the preferred embodiment of the invention:

FIG. 1 is a front elevation of a carpet roll handling device embodying the present invention;

FIG. 2 is a plan view ofthe same;

FIG. 3 is an end view showing the device moved into position to elevate a roll of carpeting; and

FIGS. 4 and 5 are detail viewsof portions of the device to be referred to.

The present invention contemplates a novel device for handling large rolls of heavy carpeting during the cutting and laying of the carpeting in a manner such as to greatly facilitate the handling the-reof; to reduce to a minimum manual lifting operations of the carpeting roll; and to reduce the time and consequently the labor. cost in laying carpeting over large door areas, such as occur in large halls, hotels, 'restaurants and the like.

Prior to the present invention it has been the practice to transport the relatively heavy, large diameter rolls to the room where the carpeting is to be laid on a small wheeled truck or dolly whereupon the carpeting was manually unrolled over the floor area to be covered whereupon the desired length was cut off. Thereafter, the roll was carried to a position to permit further unrolling and cutting. Since the carpeting may come in rolls of from eighteen to twenty-four inches in diameter and up to fifteen feet in width weighing up to one thousand pounds, such handling of the carpeting rolls is both laborious and timeaconsuming and also adds considerably to the cost of laying the carpeting.

In accordance with the present invention, provision is made for mounting t-he roll of carpeting on an elongated tube extended through the roll and then elevating the roll a short distance above the oor to permit withdrawal of the material from the roll. After measuring and cutting oi the length of carpeting required for one portion 3,3%,964 Patented Mar. 26, 1368 of the door to be covered, the elevated unit may be easily moved to another portion of the door to be covered. T-hus, manual 'lifting of the roll from one .position on the door to another is eliminated and unrolling of the carpeting by rolling it along the hoor is also eliminated. The present device is 'also particularly useful in unrolling and measuring carpeting in a relatively small room where the length to be cut, including the diameter of the rolfa, is greater than the space available in the room, thus requiring shifting of the roll forwardly and further unrolling to measure olf the length required for the length of the small room. With the present device the desired measured length of carpeting may be withdrawn from the elevated p roll and cut off without shifting the position of the roll.

Referring now to the drawings and particularly to FIG. l, the numeral represents a roll of carpeting having a tubular rod 12 extended therethrough, the ends of the rod 12 being supported on jacks indicated generally at 14. In practice, the carpeting is generally rolled onto a central tubular core member, not shown, and through which the rod 12 is extended. One end of the rod 12 has spaced I oollars 16 fixed thereto providing a grooved portion 18 into which the swivelled rod supporting end 20 of the jack is fitted as shown. The other en-d of the tubular rod 12 is smil-arly provided with spaced collars 22 but which are removably secured to the rod, as by thumb screws 23, after the same has been extended through the centr-al core on which the carpet is rolled. The collars 22 likewise provide a grooved portion 18 into which the upper swivelled rod supporting end 20 of the second jack is tted. The tubular rod 12 is herein shown as constructed in telescopically fitted sections connected together by bayonet joints, as indicated at 24, so as to accommodate carpeting rolls of various widths ranging from four feet six inches in width to fifteen feet in width, for example.

The illust-rated jacks 14 comprise double screw jacks, herein shown as having a casing 26 mounted on a base member 28, the casing having a nut 30 mounted at the upper end thereof for cooperation with the square threads of an outer screw 32. A smaller diameter inner screw 34 also having square threads is threadedly, engaged with internal threads of the outer screw 32. The nut 30 has a bevel gear 36 formed integrally therewith which meshes with a bevel gear 38 mounted for rotation in the casing 26 and provided with a laterally extended portion 40 having a yrectangular opening in the end thereof to receive the end of a crank 42 for rotating the nut 30. The upper end 20 of the jack is mounted to swivel in the upper end of the inner screw 34, as shown in FIG. 4, so that the screws may lrotate relative to the rod supporting end 20 during elevation and lowering of the carpeting. In operation, the inner screw 34 is initially fully seated in the outer screw, and yupon engagement of the rod supporting end 20 with the rod and rotation of the nut, the outer and inner screws are elevated without rotation of the screws. When the outer screw reaches its full extent of elevation, the latter is arranged to rotate with its nut 30 and thus effect elevation of the inner screw.

The base member 28 is generally A-shaped in plan view and is provided with a plurality of rollers 44, herein shown as three rollers, for the purpose of moving the unit from one position to another. The base member is also provided with adjustable elevating screws 46 provided with' foot members 48 in which the screws may rotate as shown in FIG. 5. The upper ends of the screws are provided with handles 50 to facilitate rotation of the elevating screws. In operation, the screws are initially in their retracted position, and after the carpet roll suo porting unit has been rolled to a desired position, the screws are rotated to lift the base member 28 and its rollers 44 oif the oor.

As herein shown, the A-shaped base member 2S is providedwith diverging legs 52 connected at one end by a leg 54 forming the top of the A. The casing 26 extends upwardly from the leg 54.

In operation, the tubular rod 12, which may be either a single rod or a section-al rod as sh-own, is extended through the core members, and the collars 22' are scoured to the outer und of the rod. The jacks M in their lowered position are l:hen aligned longitudinally with the ends of the carpeting roll and are rolled inwardly until the swivelled end portions 20 are aligned with the grooved .portions 18 of the supporting rods 12. The elevating screws 46 are then rotated to lift the rollers 44 oft the oor. The jacks 14 are then operated to lift the roll of carpeting off the oor a distance sucient to permit Withdrawal of the material which is measured and cut to length. Successive lengths of carpeting may be measured and cut While the supponing unit is disposed in one position or the supporting unit may be rolled to another position after retraction of the elevating screws d6.

It will be noted that the spread of the legs 52 of the base member 28 is such as to provide ample clearance around the underside of the roll of carpeting to permit the legs to be moved under the circular ends of the roll for maximum support to prevent inward collapse of the jacks and to further provide ample support to permit withdrawal of the carpeting without effecting tipping of the jacks forwardly in the direction of pull of the carpeting. In practice, the leg 54 of the base 28 may be extended forwardly as indicated at 56 to further stabilize the elevated unit. As illustrated in FIG. 4, the swivelled end 2G of the jack may be semicircular to tit into the grooved portion ll8 between the spaced collars and the semicircular portion may be provided with ball bearings 58 to facilitate rotation of the roll during withdrawal of the carpeting.

As shown in full lines in FIG. 3, the large diameter roll 10 of carpeting initially rests on the door whereupon the jacks 1d are rolled into position en-dwise of the roll, the initial position of the rod-engaging member being shown dotted at 20a. The elevating screws d6 are then rotated to lift the rollers 44 olf the floor and to engage the member 20 in its groove 1S, or the jacks may be operated to elevate the members 20 into their grooves. Thereafter, the jacks 14 are operated by the crank d2 to elevate the carpeting roll to the position shown, the elevated position of the rod-engaging member being indicated in dotted lines at 20h. In practice, the carpeting may be withdrawn from the underside of the roll, as indicated by the arrow, but it will be apparent that the carpeting may also be withdrawn from the top of the roll depending on the direction of withdrawal or the direction in which the upper surface of the rolled carpeting faces in the roll.

From the above description it will be seien that the present device greatly 'facilitates the work of the carpet layer in handling large rolls of carpeting whereby manual lifting of the roll from one position to another is eliminated by virtue of the roller mounting for the support, and manual unrolling of the carpeting along the oor is also eliminated by virtue of the elevated support by which the carpeting may be withdrawn and cut to length. Although the jacks for supporting and elevating the carpeting roll are herein shown and described as coinprising screw jacks, it will be apparent that other types of jacks, such as hydraulic jacks, may be used with ad.- vantage.

While the preferred embodiment of the invention has been herein illustrated and described, it will be understood that the invention may be embodied in other forms within the scope of the following claim.

Having thus described the invention, what is claimed is:
